Application filed December 10, 1914. Serial No. 876,406.

To all whom it may concern:

Be it known that I, FRosT V. SIMPSON, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have'invented new and useful Improvements in Box Forming and Sealing Trays, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention has for its object to provide a tray for use in sealing fiber boxes and the like, to square the folds of the box and to hold the box flaps in their proper relation after the adhesive has been applied thereto and to assist in inverting the box so as to rest the weight of the contents upon the sealing flaps while the adhesive is setting.

lVith the above and other objects in view the invention consists in the box forming and sealing tray as herein claimed and all equivalents.

Referring to the accompanying drawings in which like characters of reference indicate the same parts in different views, Figure 1 is a perspective view of a box forming and sealing tray constructed in accordance with this invention; Fig. 2 is a similar view thereof as applied to the box; Fig. 3 is a similar view thereof after inverting the box and in position for removal from beneath the box; Fig. 4c is an end view thereof; Fig. 5 is a longitudinal sectional view thereof; and Fig. 6 is a plan view thereof.

In these drawings 10 indicates a rectangular tray having side flanges 11 along three edges thereof and extending at right angles thereto, the fourth edge of the tray having no flange. The edges of the flanges 11 are stiffened and strengthened by being turned around a U shaped rod 12 while the middle flange carries a handle 13.

In use a fiber box 14 of such dimensions as to exactly fit within the flanges of the tray but extending about one third its length beyond the unflanged edge of the tray is packed with the contents to be shipped therein and after the sealing flaps of said box have had an adhesive applied thereto and are folded together the tray of this invention is slipped therein, the true flanges of the tray serving to shape the folds and corners of the box. As soon as the tray is fitted in place on the box the handle 13 is grasped with one hand While the bottom of the box is engaged by the other hand and the box is inverted and gently lowered into position on the floor or onto other boxes as shown in Fig. 3, the tray still holding the freshly glued flaps in their proper place to maintain the true shape of the box and with the rear edge of the box resting on the floor or other support and the front edge of the box slightly raised the tray is gently drawn out from beneath the box without disturbing the shape of the box and the box is allowed to settle in place and remain at rest until the adhesive has set.

By means of this invention the sealing of boxes is greatly facilitated enabling the work to be done quickly and shaping the box to its true rectangular form. The tray not being required to remain in place while the glue is setting is available for use with the next box as soon as it is slipped from beneath the box just sealed and inverted and placed in position for setting the glue.

What I claim as new and desire to secure by Letters Patent is:

1. A box forming and sealing tray, comprising a rectangular metal tray having flanges projecting from three edges thereof at right angles thereto and adapted to be placed upon the folded glued sealing flaps of a fiber box with its flanges fitting the walls of the box to shape the same and permit the box to be inverted to bring the weight of the contents on the sealing flaps thus positioned while the tray is drawn from beneath the box.

2. A tray for forming and sealing packed fiber boxes, comprising a rectangular tray member of the width of the box and approximately two thirds of the length of the box, flanges projecting from three edges of the tray member at right angles thereto to fit against the walls of the box and form them to a true rectangular shape while the sealing flaps of the box are freshly glued and folded, a U shaped rod around which the edges of the flanges are turned for hold- I sealing flaps, said handle also serving as a ing the flanges rigid, and a handle on the In testimony whereof, I aflix my signa- 612d flange of the tray by means of bWhich ture, in presence of tWo Witnesses. t e tray may assist in invertin the 0x to bring the Weight of the contefits onto the FROST SIMPSON" Witnesses:
